i've had the musket and the pharaoh. the musket is a tweaked out russian muff with an lpb-1 in front of it, the pharaoh is also a modified muff which lets you select the clipping diodes, and the algal bloom if i recall correctly is an electra distortion into a bazz fuss.

the musket is a cool muff, higher gain than the pharaoh, but the pharaoh is more of a massive kick you in the balls wall of sound hammer smash. loved mine. and it lets you switch between silicon diodes, germanium diodes, or no diodes.

i think for what you're after, the pharaoh will be the best. it stacks well. just leave the gain up on full and use the high gain/low gain switch to select your gain intensity. and roll tone all the way down and highs all the way up to get that gigantic wall of sound boosted mids awesomeness.

man i do kinda miss my pharaoh now...

that said, check out the earthquaker devices hoof out as well. it's a hybrid (silicon and germanium and LED) russian muff. sounds huge (didn't compare it to the pharaoh because i didn't have both at the same time) and you can use the shift to dial in/out your mids. not really that high gain, but it's bloody versatile. it also has great note clarity. mine is pretty much indispensable.
